PICTURE-EXHIBITING MACHINE.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed August 26, 1908. Serial No. 450,288.

To all whom it may concern:

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States,residing in Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inPicture- Exhibiting Machines, of which the following is a specification.

This invention relates to picture exhibiting mechanism, and has for anobject to provide means for serially exhibiting pictures, and isparticularly adapted for displaying pictures which are mounted on cards,and when the cards have pictures on both sides for displaying in orderedsuccession the pictures on one side of each card in the series and thenin the same order displaying the pictures upon the other sides of thesame cards.

The series of cards will be compactly ar ranged upon a carrier and inturn will be taken from their carrier, displayed at an exhibition point,and returned to the carrier with the sides in reversed position.

The rotary carrier will have substantially radial slots for receivingpins on the cards, and the track for these pins past the exhibitionpoint and back to the carrier will be so shaped that the cards willleave the carrier slots quickly and in a substantially straight linefrom their idle position, and when free from the carrier be movedquickly into position at an appreciable distance from the group of cardsstill in the carrier.

The mechanism for displaying the cards at the exhibition point will beso timed that the pictures will be moved quickly into and out ofposition and be halted at the exhibition point a sufficient length oftime to afford'the observer ample opportunity to view the picture.

lVhen the mechanism is coin or check controlled it will embody suitableclockwork to time the length of exposure of each picture, and a stopmotion operable upon the display of a predetermined number of pictures.

In the drawings accompanying and forming a part of this specification apracticable embodiment of a form of my invention is illustrated.

Figure 1 of such drawings illustrates an end view of the mechanism and avertical section of the housing for the same. Fig. 2 is a front view ofa motor and of clockwork for controlling the same.

This view also shows broken away connections with the picture exhibitingportion of the mechanism. Fig. 3 is a perspective view of one of thecards for the mechanism, a card being shown in elevation in Fig. 1. Fig.4 is a plan View of the gearing shown in the upper portion of Fig. 1.Fig. 5 is an edge view or front view of the gearing shown in Fig. 4.Fig. 6 is an underside view of the picture carrier, the forwarders forthe picture, and the track in which cards are moved by the forwardersfrom the carrier into the exhibition point and back to the carrieragain, and in this latter movement the card may, if desired, bereversed. The scale of Figs. 4, 5 and 6 is larger than that of Figs. 1and 2. Fig. 7 is a diagram showing the various stages of travel of acard in going from the carrier to the exhibition point and back to thecarrier again, the sides of the card being reversed between the time itis moved from the carrier and is again delivered to the carrier; andFig. 8 is adiagram showing the position of three cards at the same time,one of which cards isbeing moved from the carrier on to the track,another card is at the exhibition point, and the third card is beingmoved from the track and returned to the carrier.

The mechanism herein illustrated is shown as mounted in a housing,designated in a general way by 10, and which housing has a window 11 inthe front of it. This window is what will, in the illustrated form ofconstruction, be the exhibition point. This position is indicated indotted lines bearing the same reference character in the diagrams and inFig. 6. The mechanism for moving the pictures irrespective of the motorand clockwork mechanism is mounted upon a base plate 12. This base platein the present illustration divides the housing into an upper and alower compartment. In the lower of which compartments there isillustrated diagrammatically a spring motor 13, the outwardly projectingdriving shaft 14 of which carries a connecting pin or wrist 15 whichengages a coupling member 16 carried by the driving shaft 17 of thepicture moving mechanism. The shaft 17 carries a pinion 18 which mesheswith an idler 19, and the idler is in mesh with a gear wheel 20 which isfast with one of the forwarder shafts 21. The gear wheel 20 is in meshwith a gear wheel 22 which has fast with it a pinion 23 which mesheswith a gear wheel 24: which is fast with the other forwarder shaft 25.The size of the various gear wheels is subsidiary to the fact that therotations of the driving shaft from the motor will be utilized to thebest advantage and that the forwarder shafts will both be driven in thesame direction, their direction being indi cated by the arrows 210 and250.

The picture holders or cards for display ing pictures will be made ofsome suitable material, as for instance, wooden. boards which will notwarp, or some suitable paper stock, thin metal or plastic material mayalso be employed with advantage. These picture holders or cards aredesignated,

without preference, by the reference character 30 and are provided atthe upper ends with pins 31 having enlarged heads 32. The pins in thepresent instance are fastened to the board by means of clips 33 whichwill be pinned or riveted in position. Suitable clips 34: may befastened to the cards for holding pictures 35 in position. The pictureswill be in most instances located upon both sides of the cards. Byhaving clips or some suitable fastening device on the cards the picturesmay be changed from time to time as occasion may demand without thenecessity of changing the cards 30, but, of course, it will readily beseen that the pictures may be made directly upon the cards 30, or inother words, that the pins 31 may be applied directly to cards havingpictures upon them. Each pair of pins will be connected together withsufficient rigidity to permit the moving mechanism to properly act uponthem. It is not necessary in all instances that the members designatedas cards should be stiff and unyielding, since it will also be feasibleto hang cards of a flexible nature from the ins. p The carrier for thepictures in the present instance comprises a rotary member 36 which isfast upon a shaft 37, such shaft has fast upon it a gear wheel 38- whichmeshes with a pinion 39 fast with a larger pinion 40 which meshes with apinion 41 fast to the gear wheel 20. The arrow 380 shows direction ofrotation of the carrier and of the gear wheel 38. The relative speed ofthe carrier as compared with that of the forwarders will be low, thetrain of gears being constructed for reducing speed. The picture carrieror card carrier has a series of slots 42 cut inwardly from its edge forreceiving the pins 31 and supporting upon its upper face the heads 32.The slots will be sufliciently deep inwardly of the wheel 36 to permitof both pins being received within the slot. The slots are each formedat a slight angle to the radius line of the carrier, the outer endprojecting toward the direction of carrier movement, this is to affordgreater ease in moving the pins out of and into the slots.

Without going at this time into the exact itinerary of a card in itsmovement from the carrier to exhibition and back to the carrier, it willbe stated that each of the forwarders has upon it three arms, and one ofthese arms will engage one of the pins upon a card and cause such pinsto pass from the carrier into the track which is represented adjacent tothe carrier in Fig. 6;-

The forwarder will be halted momentarily in such a position that apicture will be exposed at the window 11, otherwise termed theexhibition point, the mechanism will again be permitted to moveresponsive to the motor, another arm of the forwarder will engage theother pin and advance the card into a position where an arm of the otherforwarder will engage the pin'and carry the card around the remainder ofthe track, and place it in the carrier so that its respective sides havebeen reversed in position from that it previously occupied on thecarrier.

The spring motor 13, before alluded to, will, after it is wound up insome suitable manner, as by means of a key 43, have a tendency to imparta continuous movement to the picture exhibiting portion of themechanism. There is shown fast with one of the idlers, in the presentinstance that which embodies the gears 22 and 23, a stub shaft at whichhas upon it a pin 45 for the engagement of a detent 4*.6 controlled bythe clock movement. The detent 46 of the clock mechanism is mounted upona lever 47 which is in the path of movement of tappets 48 upon a wheel49 of the clockwork. A

suitable spring 50 will hold the lever 47 in such a position that itsdetent 46 will normally be in the path of movement of the pin 45, andthus hold the parts in an idle position. The clockwork will be held idleby means of a detent 51 engaging the fly wings 55 which are connectedwith some fast running spindle of the works. The detent 51 is connectedwith a tripper 52 which lies in the path of movement of a cointraversing the coin chute 53. A coin chute of conventional form is hereillustrated, although it will be obvious that this is no part of thepresent invention.

When a coin traverses the coin chute and engages the tripper 52 thedetent 51 will be withdrawn from the pat-h of movement of the fly wingsand this will permit the wheel 4:9 to rotate and its tappets to raisethe lever 47 and disengage the detent as from the pin 45. Each movementallowed the exhibiting mechanism will be suflicient to cause the armscarried by the forwarder shaft 21 to remove a card from the carrier andbring this to the exhibition point.

The detent 46 will, between each such move ment fall responsive to itsspring 50, and will be again interposed in the path of movement of thepin 45 and stop this rotation and stop all the mechanism for asufficient time to permit the person who has dropped the coin in themachine to get a view of the picture, after which the detent 46 will beagain removed from the path of movement of the pin 45 and another cardwill be advanced to the exhibition point and the former card returned tothe carrier.

Upon the stub shaft 44 is a pin 56 which will engage with the teeth of awheel 57 moving this one tooth distance at each rotation. There is fastwith the wheel 57 a cam 58 which engages an arm 59 connected with thedetent 51, so that upon a complete rotation of the wheel 57 the arm 59will enter into the notch 60 of the cam 58 and the detent 51 will bebrought into the path of movement of the fly wings and the mechanismwill cease to operate until another coin is placed in position.

When it is desired to move one of the cards from the card carrier 36 tothe exhibition point and back again to the card car rier, the pins 31will be moved from the slot 1 42 into a trackthe track has severalportions which will be referred to by means? of suitable referencecharacters, and to avoid confusion the entire track will not be givenany reference character in this description.

As was above stated Fig. 6 is an underside view and consequently themember 36 isshown as rotating so far as the plane of the paper isconcerned in a reverse direction to that in which the shaft 37 whichcarries it is shown asrotating in Fig. 4, see the arrow 380.

In describing the movement of the cards reference should be had moreparticularly to Figs. 6 and 7. A card will be assumed to be in the slotmarked T, that is, its pins will be in such slot. The rotation of theshaft 21 will cause the forwarder arm A, which initially occupies inFig. 7 the position a, to

engage the pin which is at the inward end of the slot T and is at theposition marked 1 when the slot T is at the position 1 The position 1 ofthe slot T will be opposite the portion 60 of the track and the forwardmovement of the arm A to the position a? will advance the engaged pin tothe position 2, and will move the other pin from a point near theperiphery of the carrier, that is from the point 1 to the point 2, wiichis beyond the periphery of the carrier and onto the track 60. An advanceof the forwarder arm to the position a will move the engaged pin to theposition 3, within the periphery of the carrier, and the other pin whichis in the track to the point 3 and in engagement with spring 61 whichspring acts partly as a-detent and partly as a back stop to prevent theretrograde movement of the pin. This spring and also the spring shouldbe suficiently delicate so as to practically interpose but littleresistance to the passage of the card. The slot T has now advanced tothe position 2 Further advance of the carrier 36 will bring the slot Tto the position 3*, which brings such slot into alinement with theportion 62 of the track. An advance of the forwarder arm to the positiona will move the engaged pin to the position 4, past the periphery of thecarrier and into the portion 62 of the track. This movement will haveadvanced the other pin to the position 4, the spring will be flexed andwill to a certain extent retard the movement of the pin. The forwarderarm will then move to the position a and move the engaged pin to theposition 5 and the other pin to the position 5. Further advance of theforwarder arm to the position a will move the engaged pin to theposition 6 and the other pin will remain at the position 5 and 6. Up tothis last movement the card has been moved by being pushed by theforwarder engaging the rearward pin. Now the advance pin pivots and therearward pin becomes the advance pin, and movement of the forwarder armto the position a will drag the pin which has now become the advance pinto the position 7 and the other pin to the position 7 in the portion 63of the track. The forwarder arm will now advance to the position a atwhich position it will move the pins to the positions 8 and 8respectively, opposite the exhibition point 11, hereinbefore alluded to.Atabout this point the forwarder arm A will slip off of the pin withwhich it has been in engagement and move to the position a where it isout of engagement with the pin. At about this time the detent pin 45engages the detent 46 of the time or clock mechanism and the pictureexhibiting mechanism is brought to a rest for a sufiicient length oftime to permit a view of the picture. This time is gaged by the intervalof time required for another tappet 48 to raise the lever 47 and efiectthe release of the detent 45 and for the mechanism to respond to themotor. The card is brought to rest with pins in the portion 64 of thetrack and with one of the pins past the point or toe 65 of the switchtongue which switch is pivoted at 66. The arm 13 will now come into theposition marked B engage the rearward pin, and move the pins frompositions marked 9 and 9 respectively. The advance of the forwarder armto the position B will move the pins to the positions 10 and 10respectively.

In the advance pin moving from the position 9 to 10, it will engage theheel 67 of the switch and move the toe 65 into the portion 64 of thetrack, opening up the portion 68 to the passage ofthe rearward pin. The.ad-

vance pin at 10 having started upon the portion 69 of the track,movement of the forwarder arm to the position 3* will move such advancepin along the portion of the track 69 to the point 11 and the rearwardpin or the pin with which it is in engagement to the point 11 and to apoint where it has passed the other heel portion 67 of the switch andhas thrown the switch to its initial position, namely to open theport-ion 64 of the track. A further movement of the forwarder arm to theposition B moves it out of engagement with the pin and for-' wards thepins slightly to such a position that the forwarder arm C will atposition C engage the rearward pin and move the pins to the points 12,12 respectively, it arriving at the position C from which position itwill move to the position C moving the pins to the points 13, 18respectively. A further movement of the forwarder arm to the position Cfwill bring the advance pin to the point 14: and against the spring 70.The rearward or engaged pin will be moved from the point 14 to the point15, the other pin remaining at the point 14, 15, about which the cardwill fulcrum or pivot, and in the movement of the forwarder arm from theposition (1* to the position C the relative positions of the pins willbe changed so that the pin which was heretofore the rearward and pushedpin will now be the advance and dragged pin. The movement of theforwarder arm to the position C will move the pins to points 16-46respectively and at such a time that the portion 71 of the track is inalinement with the slot U when it is at the position 1*. A slightlyfurther advance of the forwarder arm to the position C will move thepin, which is now the advance pin, from the point 16 to the point 17just within the perimeter of the carrier; further advance to theforwarder arm to the point C will move the engaged pin to the point 18and the rear pin to the point 18 which is in the portion 72 of thetrack. The slot U will at this time occupy the posi tion 5 and will moveto the position 6 which will bring it opposite the portion 72 of thetrack, after which a movement of the forwarder arm to the position Gwill move the engaged, the advance,pin to the point 19 which is at theextreme inward end of the slot U and at the same time moving therearward pin to the position 19 within the perimeter of the carrier.

The carrier, during the above described movement, will make an angularadvance of a distance indicated by the lines TV and J in Fig. 7 And thecard which will have been exhibited has been moved upon the carrier to aslot which is the seventh slot from the one which it at first occupied;it being taken from T, Fig. 6, and returned to U. Each card in passingthrough the portion 60, 63

and 62 of the track is drawn quickly away from the other cards in thecarrier and is reversed, and it is moved quickly into the carrieralongside of previously returned cards and is again reversed in passingthrough the portions 69, 68, 71 and 72 of the track, so that the nexttime it is presented at a point where it will be engaged by theforwarder and advanced to the exhibition point the opposite side will beexhibited. For this reversal feature of exhibiting its alternate sidesthe card must either be given a half turn or a turn and a half, thepresent track will effect the latter movement so far as the movement ofthe card relative to the track is concerned, but so far as the movementof the card relative to its first position is concerned it will havemade but half a turn, it making a quarter turn each time its pins arereversed in thetrack.

The slots 42 of the carrier are substantially radially disposed, forconvenience however they are disposed at a slight angle to the radius ofthe carrier. The track portions 60 and 62 at their receiving ends willaline with the slots to facilitate movement of the pins into the track,these portions of the track, then quickly turn from such line forturning the cards being moved away from the other cards in the carrier.Cards much wider than the distance apart of the pins 31 may be employedwhen the move ment of the removed card is sufliciently' rapid to get itout of the path of movement of the oncoming cards. By having the pins 81placed relatively close together the space occupied by the track may bereduced materially.

In Fig. 8, one of the cards is shown at the position indicated at thepoints 8, 8 which is the exhibition point. Another card is exhibited atthe points 16, 16, where it is being received by the carrier, andanother card is exhibited at the points 2, 2 where it is being removedfrom the carrier. While the forwarder arm B is moving the card t, whicharm A removed from the slot T of the carrier, past the switch, arm Dwill be moving another card 0), from the slot V. The arm E of the otherforwarder will, at this time, be returning a card 8, which was takenfrom slot S by arm B and moved from the exhibition point by arm D, toslot R. Card 0 will be moved from the exhibition point by arm A andreturned to the carrier at slot Q by arm F.

Some suitable means will be employed for holding the switch toe 65 ineither one or the other of its positions. A convenient means foraccomplishing this is a leaf spring 73 which will engage the heel of theswitch, and be carried by the framework.

In the present instance the track is shown as having undercut edges forthe accommodation of the heads 32 of the pins.

After a predetermined number of cards has been exhibited, in thepresent'instance the number indicated by the teeth of the wheel 57, thelever end 59 will come into the cam notch 60 and the clockwork will bestopped and the mechanism will remain stopped until such time as it isstarted, as for instance by a coin traversing the coin chute 53.

F or the purpose of assuring that the pins be properly located in theslots, both.before The various positions of the cards indi cated in Fig.'7 have required so many reference characters that the track which isthere indicated by single lines has not been given the referencecharacters above referred to. These portions, however, have beenindicated by reference characters in Fig. 6, which, it is believed, willbe ample for the present description.

'The card carrier, which in the present instance has been shown anddescribed as circular and rotary, has the slots for the pins extendinginwardly from its perimeter a distance less than the width of the cards,that is each card is of a greater width than the length of each of theslots and the pins will consequently be set inwardly of the edges of thecards.

A plain track without the shunt portions for detaining the then forwardpin and permitting the rearward pin to pivotabout the said forward pinand in passing to the fore reversing the card, will give the card a halfturn. The shunts herein described will each give the card a half turn,the net result being that the card will be placed in the carrier withits sides reversed so at the next exhibition movement a differentpicture will be brought to the exhibition point. But by simply changingthe position of the switch tongue so that the then forward pin passesinto the portion 68 of the track, the net result of the passage will notbe a reversal of the card and at the next exhibition the same picturewill be brought to the exhibition point.

In Fig. 6 of the drawings the top edge of one of the cards is seen inthe broken away portion of the carrier and the side of the card whichhas just been exhibited is indicated by the reference character 310 andthe side of the card which will be exhibited at the next exhibitionmovement is represented by the reference character 300.

The shunt portions of the track move the cards'much more rapidly awayfrom the carrier. than will a plain track. The card or other exhibitingdevice is given the resultant of a compound movement, one component ofwhich is laterally of the card, which lateral movement is an importantfactor in getting the moved card out of the way of the next and oncomingcard in the carrier.
